Appliance Coil Brush, For All Models, AB-141

I have had trouble for years getting the coils under my refrigerator clean. I have built thin vacuum extensions, made brushes, tried all types of things. But every few months, the food in the fridge starts to freeze, and I have to do the puny amount of cleaning that I was able. I ordered this brush because I thought it was flat. When it arrived, and I saw that it was round, I was sure it wouldn't work. The space to put the brush through to access the coils is only about 1/2 inch by 3/4 inch. To my surprise, this brush did an amazing job! Coupled with a vacuum as I used the brush, it cleaned the coils better than I EVER have before. The brush itself is very well made. It even has a rubber tip over the center to minimize the possibility of damaging the coils. I know this sounds too good to be true, so I've attached a few photos. The area on the right has already been brushed, which the area on the left has not. You can see the difference clearly. I would recommend this brush strongly!
